A.Application tiled March 1, 1922. Serial-No. 540,313.

To all whom it may concern Be it known that I, HARRY L. HUssMANN, a citizen. of the United States, and residing at St. Louis, Missouri, have invented the new a and useful Improvement in Showcase Refrigerators, of which the following is a speciiication.

This invention relates to refrigerators, and more particularly to show case refrig- .ttr erators, such as shown and described in Patent No. 1,225,682, patented May 8, 1917 and in my application Serial Number 463,- 250, filed April 2l, 1921.

In this type of refrigerator a compart le ment is provided for the refrigerant or freezing mixture container and a side door is provided through ywhioh'said container may e removed. lt has been found in practice that considerable moisture condenses on the 2o interior surface of the door and walls on the adjacent side ofthe container and the drip pan. This is due to the fact that the refrigerant or freezing mixture container has a metallic wall which is opposite but close 2t to the door, and that this container is constructed and positioned to cause circulation of air between the wall and the door and also in and around the /drip pan positioned between the Wall and the door. so culating air from the show vcase compartment, of course, contains considerable moisture, which will condense on the extremely cold metal wall of the container and upon the metal pan and the inside door face close to the container wall and in the path of the circulating air.` The moisture,- after trickling down the interior surface of the door, may drip upon the sill and will sometimes creep along the sill to theoutside of the refrigerator and leak through thc door opening.

@ne of the objects of this invention, therefore, is to -provide means whereby such leakage of the water of condensation through the door opening may be prevented.

Another object of this invention is to pro-f vide means for draining thedrip water from the door sill to the inside of the compartv ment so as to prevent lodgem'ent of the water an' on the door sill and the consequent rotting of thev sill.

' Another object of this invention is to provide a pan mounted and arranged for catching the drip from the container whenl the te latter is moved out of the'refrigerator.

This cir- .Further objects .will appear from the detail description taken in connect-ion with the accompanying drawing, in which:

igure 1` is a. sectional view taken at the refrigerant container compartment, showing a refrigerator embodying this invention;

Figure 2 is a' detail view showing the means of securing the drip pan in raised .position v Figure 3 is a detail showing the construction of the hinge of the drip pan, the shape ofdthe sill, and the drip edge on the door; an

Figures 4f and 5 are details of the hinge construction for the drip pan.

Referringto the accompanying drawing. l'designates the refrigerator casing within which is a compartment 2 for the refrigerant container 3, from which the drippings fall.

These may be of the construction described and illustrated in the above-mentioned patent and application. The container 3 is provided with rollers 4 adapted to run on tracks 5, suitably supported within the compartment 2 and extending to the door opening. The door 6 is hinged to open sideways to allow the removal of the container. Hinged to the'track 5 near the end thereof is adrip pan-7. The panl 7 is provided with 11p-turned flanges on three sides thereof so as to retain the drip water. The fourth side is provided with an extension Sadapted to extend within the door-way when the pan is lowered, so as to discharge or drain the drippings within the compartment 2. The

pan 7 is reenforced at the edgesithereof by a' pair of rails, (only one of which is shown), adapted to reenforce the pan. A cleat 10 is fixed to each of the rails 9 and extends beyond theend of said rail, being hinged at 11 to the track 5. This provides a hinge vuponl which the pan 7 may be lowered whenl it isvdesired to remove the container 5, the container being run out over the pan directly therebcneath in order that the latter may catch the drippings therefrom, which drain into the compartment.

When in lowered position the pan ,may be additionally supported by a toggle l2 suitably hinged to the pan 7 at one end and to the 'refrigeratorr casing at the other. The

pan may thus be folded on the hinge 11 into the door-way and to a osition within the compartment 2 alon side of and against the. container 3, as i1 ustrated in Figure 1,

,in which position it may be secured oy an arm 13 engaging a recess 1% in the easino'. l* The inner wall of the door 6 extends over sill l formed`on the lower easing wall.

5 This sill is provided with a eurved or slop- `15 along* the inner edge of the door.

iigssurt'aee sloping` downwardly toward the interior of the compartment 2 so that water dripping thereon may flow inwardly into said Compartment. The surface of the sill Y 1Q may be protected 'by a Acovering; 16 which with a weather strip 19 adapted -to more yeffectively seal the door opening.

It. will, thereforerhe seen that. oy this eonstruetion all leakage ot' the eondensation water to the outside of the refrigerator eas- 25 ing may be prevented. The water resulting;-

that surface to the drip edge LS and heiner from the/moisture present in the circulating air 'coming from the show eziee compartment condensing on the drip pan and on the interlor sur-ffice of the door 6 triekles down unableto creep along the nnder sinfare ol the door (i on aerount of the groove 1T. will drip ofi' oltlieedge 18 on to the sill 15. (lo

account of the sloping;r eontour ot' the sill 36 15, the Water will drain therefrom inwardlj.Y

' 40 rotting thereof. vVhen the pan i into the compartment Q, the covering- 16 lieinp; effective in preventingV saturation of -tlie Wood or other material of which the easing' may be constructed and eonsequen M is lovv'ered vfor the removal of the container' 3, the extension 8 provides for conducting the drippings taught by the pan to the interior of the refrigerator.

It is obvious that various Changes may he limade in details of eonstruetion without dearting from the spirit. of this invention; it is, therefore,v to be understood thatr this invention is vnot; to he limited to the speeiiie details shown .and dee'erbed.
